Ultrasonic RADAR - Uses an ultrasonic range finder to measure the distance to surrounding objects (resolution better than 0.1 inch!). A stepping motor rotates the range finder, giving full circle coverage. Your computer paints a graphic display of the surroundings.

A normal glass pane? - Holographic ultrasonic touch screen and graphic tablett with fingerprint recognition.

Ultrasonic Blaster - sonic shockwaves

Ultrasonic/Contact Stethoscope - The 2047U/C combines the features of a standard electronic stethoscope - with those of an ultrasonic (sounds higher in frequency than the ear can hear) detector.

Thin Film Ultrasonic Transducer for Accurate Control of Fastener Clamp Load - NASA (USA)

Ultrasonic Translator SK-207 (Transtronic) - (Electronic Kit) Hear car brakes, gas leaks or even bats!

The Paper Chase (Discover - Science News) - Focused blasts of sound may be the key to saving trees and reducing the flow of garbage

An On-loom, Real-time, Noncontact Fabric Defect Detection - Argonne National Laboratory

Parametric Difference Waves for Low Frequency Acoustic Propagation - Unclassified/commercial mind control technology.

Sound velocity sensor AQSV-1500 - AQUAMATIC, Denmark

Non-contacting Ultrasonic Velocity and Attenuation Measurement System - Nondestructive Evaluation Sciences Branch Langley Research Center.

The Audio Spotlight (MIT Media Laboratory) - The Audio Spotlight (TM) uses subtle nonlinear properties of the air to create an extremely narrow sound beam. This beam ofsound behaves just like a beam of light - 'shining' it at a specific listener allows only that person to hear it, and projecting it against a surface creates an acoustic 'image' at the point of reflection. It is the first device that provides total control over both the location and distribution of high quality sound, something impossible to achieve with traditional loudspeakers.

Method and device for manufacturing hot dogs using high power ultrasound - United States Patent: 6,146,674

Ultrasonic power sensory system - A system includes a first transducer and a second transducer coupled together through a coupling medium communicating undulating pressure wave from the first transducer to the second transducer for the transfer of electrical power from an external controller energizing the first transducer transducing the power signal into an undulating pressure wave communicated through the medium to the second transducer traducing the undulating pressure wave into an electrical response signal that can be converted into useful power for powering an embedded sensory and actuation control unit. The primary advantage of the system is the transfer of power through a coupling medium without the use of electrical power wires. United States Patent: 6,127,942
